Have you had different roles or titles within one company and you would like to make it clear in your resume? There's a solution!
Although in the current version of the builder there is no way to add multiple roles under one company in the Experience section, you can still make it clear to the recruiter that you've had a promotion and changed positions.
To do so, open the file that you would like to edit and click on the Editor tab in the top menu.
Then within the Experience section add two separate entries for each role (with the same company but different job titles).
Another way is to add both positions in the same entry. In this case, you will need to add both job roles in the entry description.
This way it will be perfectly visible to any potential employer that you have climbed up the ladder in your previous firm.
